5.5. Where to go from here

Now that you have a working Heartbeat configuration, you will want to
continue with configuring Pacemaker and adding cluster resources.

The following documents are available for your perusal:

Clusters From Scratch
is an excellent guide for configuring Pacemaker clusters. The
document primarily covers Pacemaker on Corosync, but starting with
its chapter "Using Pacemaker Tools" applies identically to Heartbeat
clusters.

The DRBD User’s Guide has a
chapter dedicated to integrating DRBD with Pacemaker clusters.

Several Technical Guides covering Heartbeat/Pacemaker clusters for a
variety of applications are available from
the LINBIT web site.
